On Tuesday, Westbrook explained the move on ‘The Tonight Show’ with Jimmy Fallon.

“I’m pretty big for my position,” Westbrook said. “I would say I’m probably stronger than other guys at my position so when I have smaller guys on me, you have to treat them like babies. … The guys guarding me don’t love it so much but everybody else loves it.”
